Very interesting... It just dawned on me that I noticed the problem AFTER the car had a tire replaced under its road hazard warranty. It hadnt been driven in a few days, and, I really didnt think about it. The tire was replaced with an identical Michelin, but with of course no miles. It was put on the front drivers side.

So.. this now begs the question... what should I do short of putting another new tire on the front??

Thanks for the replies!
